SMOKE-CONSUMER ATTACHMENT FOR FURNACES.

SPECIFICATION forming part of Letters Patent No. 616,727, dated December27, 1898. Application filed April 1,1898. Serial No. 676,060. (Nomodel.)

To all whom it ntctyconcern:

Be it known that I, WILLIAM H. PERLEY, of Lynn, county of Essex, andState of Massachusetts, have invented an Improvement in Smoke-ConsumerAttachments for Furnaces, of which the following description, inconnection with the accompanying drawings, is a specification, likeletters on the drawings representing like parts.

My invention is an improvement in smokeconsumers, having for its objectthe provision of means for consuming the smoke and at the same timeeconomizing the consumption of the fuel by the heat developed in theprocess of the smoke consumption, my invention also including means fordeadening the noise usually accompanying this class of devices, and alsoincludes further improvements, which will be mentioned and explainedhereinafter.

In general my invention comprises an elongated steam-jet so constructedand arranged as to draw in a blast of air and mingle the steam and airat a superheating point for the generation of gases, capable of insuringperfect combustion, which are thence delivered by an adj ustably-jointeddeflector to the best advantage for the particular furnace, the suctionof air taking place through an interrupted passage which breaks thevibrations and prevents the objectionable roar and noise heretoforeattendant upon smoke-consumers of this class.

The details of construction of my invention and the operation andfurther advantages thereof will appear more fully in the course of thefollowing description, and the invention will be more particularlydefined in the appended claims, reference being had to the accompanyingdrawings, also forming part of this specification.

In the drawings, in which I have shown a preferred embodiment of myinvention, Figure 1 is a vertical longitudinal section of a furnaceprovided with my apparatus, the latter being shown in central verticallongitudinal section. Fig. 2 isaside elevation thereof, parts beingbroken away in order more clearly to show the construction. Fig. 3is acentral horizontal section thereof.'

The furnace A, having a grate a, steampipes a, boiler a and ash-pit amay be of any usual or preferred kind, my invention beingintended foruse with any furnace, heater, or other source of fuel combustion.

The smoke-consumer B is herein shown as located in the head a of thefurnace or boiler and is connected by a pipe I; with the dome of theboiler or other source of steam-supplyunder pressure, a drip-pipe b andcook 71 being provided in order that dry steam may be had, if required,and the one or more smoke-consumers, as desired, receive theirsteam-supply from a supply-pipe 19 provided with a supplyvalve 12 andpreferably also each provided with a regulating-valve The steam from thesupplypipe 1) passes through the regulating-valve b within adischarge-chamber b, in which is concentrically extended adischarge-nozzle 6 which has an opening end I), terminating aconsiderable distance within the discharge-chamber, for a purposeprese'ntly to be explained. At its outer end the discharge-chamber b isprovided with an airbox I), shown as laterally extended and provided onits inner walls with a plurality of interrupted diaphragms or staggeredpartitions 1) the air having access to the air-box at 12 Referringfurther to Fig. 3, it will be seen that the discharge-chamber b issecured for convenience by a shouldered nut or union Z2 to a nipple 5 onthe air-box and that it has an extension 6, shown as telescopicallymounted on its inner or forward end at Z9 this provision being apreferable one for the purpose of enabling the apparatus to beaccommodated to varying thicknesses of furnace-walls or to otherconditions. At its forward end the discharge chamber carries anadjustable deflector b flared at its horizontal sides, as i11-dicated'at 19 Fig. 3, and converging at its top and bottom sides, asshown at b, Figs. 1 and 2. This deflector is adjustable angularly withrelation to the discharge-chamber in order that the steam and air may beproperly commingled and directed at the precise part of the fire-boxwhere it will be of the most service. As herein shown, this adjustmentis attained by providing the discharge-chamber with curved upper andlower wings 17 receiving reversely-ciirved flanges 19 on the adjacentend of the'deflector, one or both of these being slotted to receivefastening-bolts 79 for clamping the deflector in any adjustment.

My aim in this device has been to provide means for producing moreperfect combustion than has been possible hitherto, and I have foundthat by extending the dischargenozzle a considerable distance within theheated portion of the discharge-chamber the air and the superheatedsteam, coming together, as they necessarily do under such circumstances,in an exceedingly-hot chamber and then impinging against the top wall 11of the deflector and being directed by the adjustable deflector in theprecise direction and portion of the fire'box where they will meet theproducts of combustion to the best advantage, develop combustible gasesto a remarkable extent and perfection; also, I have found that byproviding the free end of the discharge-nozzle entirely open andpreferably slightly flared, as shown at N, there is a superior sprayingeffect and the discharge-nozzle is automatically maintained open andclear of foreign clogging matter. This is of special advantage in adevice of this kind, and I find that it materially enhances the free anduniform workin g of my smoke-consumer. Leaving the discharge-nozzleentirely open permits the discharge of the steam without hindrance, sothat it has no tendency to condense, and also it has a superior force,the result being that when the commingled air and dry steam strikeforcibly against the opposing wall of the deflector a dry spray isdriven out over the fire in a most effectual manner.

I wish also to lay especial emphasis upon the air-box feature of myimproved smoke-consumer. As is well known by all who are practicallyconversant with these matters, the noise of the injector type ofsmoke-consumers is exceedingly objectionable, and accordingly theremoval of this noise is of great advantage and value. By providing theinterrupted passage-way for the entrance of the air asit is sucked in bythe steam-blast this noise is stopped and the apparatus workssubstantially noiselessly.

By adjusting the regulator 73 the proportion and amount of steam and airmay be varied as desired, and it is to be noted that the relations ofthe parts, particularly the location of the valve 12 are such that thesteam is without interruption or tendency to condense, so that a cuttingdown of the amount of steam does not produce a wet steam, butleaves thedry-steam blast the same as before. This is of considerable advantage.

Various changes in details of construction and combinations of parts maybe resorted to within the spirit and scope of my invention.

Having described my invention, what I claim, and desire to secure byLetters Patent, 15-
